Brian， I have a question, thanks. the tup code: |cic| opc| dpc| so I think all the bits of cic should be put into the User Protocol Data field of M3UA and at the same time, 4 bits of the CIC that normally overlap into the SLS field of the SS7 routing label into the SLS field in the Protocol Data parameter of M3UA?

Igor, First, can you point to somewhere in the world where TUP is still used? Next, can you indicate who in that part of the world will be running TUP over M3UA? Then, move the 4 bits of the CIC that normally overlap into the SLS field of the SS7 routing label into the SLS field in the Protocol Data parameter of M3UA and leave the other 8 bits of the CIC in the User Protocol Data field of M3UA, just as is done in SS7 between the routing label and the SIF. --brian Igor Fedotov wrote: (Mon, 25 Jun 2007 17:09:47) > > Can anyone explain how SS7 TUP messages are transported over M3UA? > The problem is in the mapping TUP Routing Label to M3UA message.
